Di-isopropylnaphthalene (DIN) and pseudocumene (PC) are also widely-used LS solvents. Especially, the LS made of DIN or PC has better pulse shape discrimination power than LAB-based LS. Adding 10% DIN into LAB-based LS also improves the pulse shape discrimination significantly [1]}, which is attractive to reject fast neutron background for an experiment with shallow overburden like TAO. These two solvents are also studied here.
